Black,² W.T. Anderson,² and C.A. Alvarez Zarikian³ Abstract Organic matter concentrations and organic carbon and nitrogen isotopes are reported for sediments drilled during Integrated Ocean Drilling Program Expedition 346. The Japan Sea/East Sea sediments from Sites U1426 and U1427 feature a range of total organic carbon (%TOC) between 0.16% and 6.36%, total nitrogen (%N) between 0.04% and 0.39%, δ¹³C values between –25.87‰ and –19.56‰, δ¹⁵N values between 3.33‰ and 13.08‰, and carbonate concentrations (%CaCO₃) between 0% and 44.29%. The East China Sea sediments from Site U1429 feature a range of %TOC between 0.10% and 2.85%, %N between 0.02% and 1.22%, δ¹³C values between –24.74‰ and 17.73‰, δ¹⁵N values between 3.59‰ and 13.40‰, and %CaCO₃ between 0.70% and 42.84%. Both organic matter content and stable isotopes are well correlated with b* sediment color reflectance values and infer decreased surface productivity and suboxic to anoxic environments during glacial periods and increased productivity and deep-water ventilation during interglacial periods in the Japan Sea/East Sea. ¹ Black, H.D., Anderson, W.T., and Alvarez Zarikian, C.A., 2018.
